Element Class Documentation
class ElementNamespace:com::datalogics::PDFL
- Derived classes:
- Container, Form, Group, Image, Path, PostScript, Shading, Text, TextRun
Detailed Description
The base class for elements of the content of a page. An element is a building block; everything in a PDF file is an element. An element object can be associated with a large amount of unmanaged memory in APDFL and should be deleted when the object is no longer in use.
Member Function Documentation
clone
Element clone()Returns:
ElementThe copied element.
Makes a copy of the element.
Make a copy of an element to obtain a new element that has a distinct set of attributes.
Note: TextRun objects may not be cloned.
clone
Element clone(java.util.EnumSet< ElementCloneFlags > cloneFlags)Parameters
cloneFlags: java.util.EnumSet< ElementCloneFlags >Flags that modify the cloning operation.
Returns:
ElementThe copied element.
Makes a copy of the element.
Make a copy of an element to obtain a new element that has a distinct set of attributes.
Note: TextRun objects may not be cloned.
delete
synchronized void delete(Boolean disposing)Parameters
disposing: Boolean
Returns:
synchronized voiddelete
synchronized void delete()Returns:
synchronized voidfinalize
void finalize()Returns:
voidgetBoundingBox
Rect getBoundingBox()Returns:
RectThe bounding box for this element. The coordinates of the bounding box are specified in user space coordinates, relative to the element's Content. Note that user space coordinates correspond to unrotated pages; any rotation specified in the page dictionary is not taken into account.
The bounding box for this element.
The bounding box is a rectangle that is guaranteed to encompass the element, but it is not guaranteed to be the smallest box that could contain the element. For example, if the element is a Path that contains an arc, the bounding box encompasses the bezier control points, and not just the curve itself.
getClip
Clip getClip()Returns:
Clip- The current Clip for this Element.
Gets the current Clip for an Element.
getMatrix
Matrix getMatrix()Returns:
MatrixThe transformation matrix for the element.
rotate
void rotate(double theta)Parameters
theta: double
Returns:
voidRotate an element by T degrees counterclockwise units using the matrix [ cos T sin T -sin T cos T 0 0 ].
scale
void scale(double sx, double sy)Parameters
sx: doublesy: double
Returns:
voidScale an element by (sx,sy) units using the matrix [ sx 0 0 sy 0 0 ].
setClip
void setClip(Clip clip)Parameters
clip: ClipThe clip to set as the current clip for this element.
Returns:
voidSets the current Clip for an Element.
setMatrix
void setMatrix(Matrix matrix)Parameters
matrix: Matrixthe transformation matrix for the element.
Returns:
voidSet the transformation matrix for the element.
translate
void translate(double tx, double ty)Parameters
tx: doublety: double
Returns:
voidTranslate an element by (tx,ty) units using the matrix [ 1 0 0 1 tx ty ].
